The Longyuan Mountain Range stretches across the west of Kyushu. The main peak, Xinglong Peak, is shrouded in clouds and mist all year round. Deep in the mountain lies a demon-sealing formation that traverses the heavens and the earth. Three hundred years ago, the door to the demon realm opened, and the demon lord led thousands of demon cultivators to break through the western realm. All living beings were devastated, and the world was stained with blood.
At that time, five monks with the five spiritual roots of gold, wood, water, fire, and earth stepped forward: the gold spirit monk forged a black iron sword to slay the demon generals, the wood spirit monk led the spiritual vein energy to protect the living, the water spirit monk gathered the four seas to subdue the demonic tide, the fire spirit monk set fire to his Dantian to burn the demon soul, and the earth spirit monk condensed the earth vein crystals to build the formation base. The five people used their own spiritual roots as a guide, supplemented by the spiritual porcelain key passed down from the Yun family's ancestors, and set up a demon-sealing array under the Awakening Dragon Peak. They finally sealed the demon lord in the eye of the array, and the door to the demonic realm was also closed.
After the war, the five spirit monks made an agreement: the golden spirit vein will guard the Xuan Iron Mine, the wood spirit vein will protect the Porcelain Workshop, the water spirit vein will guard the Qingshui Stream, the fire spirit vein will guard the Fire Tower, the earth spirit vein will guard the source of the earth vein, and the demon-sealing array will be guarded for generations. Because the spirit porcelain key became the core of the formation eye, the Yun family settled at the foot of Longyuan Mountain, opened a workshop to refine porcelain, nourished the formation base with the power of spirit porcelain, and passed down the ancestral motto of "guarding the formation to protect the world" from generation to generation.
However, as hundreds of years pass, people's hearts change. Among the five spirit veins, one of the golden spirit veins gradually became greedy. In order to use the power of the demon lord to break through the cultivation level, it secretly tampered with the flow of the black iron veins, secretly leaked the demonic energy to nourish the demon lord's remaining soul, and called itself the "Xuan Iron Sect". It hid in the Black Stone Valley and waited for opportunities to break the formation.
Three hundred years have passed in a blink of an eye, and the lavender spiritual light of the Demon Sealing Formation has gradually dimmed, and the five spirit patterns beside the formation's eyes have quietly turned black. In the clouds and mist of Awakening Dragon Peak, there is a vague sweet smell floating in the air - that is the soul-eating demonic energy of the Demon Realm, which is slowly seeping into the human world along the cracks in the earth's veins.
